Question
A shopkeeper marked the article at 30% above its cost price
and gave a 10% discount. If the cost price of the article is Rs. 1200. then what is the profit percent earned?Solution
We know that,
Marked price/Cost price = (100 + Profit%)/(100 - discount%)
(1200 x 130/100)/1200 = (100 + Profit%)/90
130/100 = (100 + Profit%)/90
Profit% = 117 - 100 = 17%
